Add event to unlock new recipes in recipe book. + grouping in recipe book.

Recommended Posts

Is there a way to make modded item's recipes unlocked in the recipe book by for example picking up crafting material for the given item?

Let's say I pick up an iron ingot and it would unlock a new recipe of modded item.

 

Also is there a way to group modded items in that recipe book? Currently, my recipes just show in the misc-tab(tab with lava bucket and apple).

I would like to move tool items under tools-tab(tab with axe and sword).

 

I'm modding for 1.15.2.

Ok I figured it out.

 

Subscribe to ItemPickupEvent and unlock players recipe based on whatever item they picked up.

 

@SubscribeEvent    
public void onItemPickup(ItemPickupEvent event) {
  Item item = event.getStack().getItem();
  if (item.isIn(Items.INGOTS_IRON)) {
    PlayerEntity player = event.getPlayer();
    ResourceLocation[] recipes = new ResourceLocation[1];
    recipes[0] = new ResourceLocation("your_mod_id:mod_item_id");
    player.unlockRecipes(recipes);
  }
}

Please do correct me if this is the wrong way to do it. It works though. I did refactor player events to their own class to handle with, but this is basically what it does in its simplest form.

item.equals() changed to item.isIn() because it's comparing to a tag.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

That would actually work in this case better with iron ingots, because you can get them in many ways. I look into it. Thanks!

 

This is then again another way to do it for custom stuff, that doesn't have advancements.

Here's a couple of examples.

You can set up your own conditions as well, I just don't have any ready examples.

Thanks Draco!

Now, do you have to add something else to make this work? Because this didn't work:

I added this json under src/main/resources/data/modid/advancements/recipes

Is my tag written correctly or is it something else for iron ingots?

{
  "parent": "minecraft:recipes/root",
  "requirements": [
    [
      "has_item",
      "has_the_recipe"
    ]
  ],
  "criteria": {
    "has_item": {
      "trigger": "minecraft:inventory_changed",
      "conditions": {
        "items": [
          {
            "tag": "minecraft:ingots/iron"
          }
        ]
      }
    },
    "has_the_recipe": {
      "trigger": "minecraft:recipe_unlocked",
      "conditions": {
        "recipe": "modid:mod_item"
      }
    }
  },
  "rewards": {
    "recipes": [
      "modid:mod_item"
    ]
  }
}

This is not an existent tag.

There is forge:ingots/iron though.

@Draco18s

Still haven't figured out how to do that grouping in recipe book. Or is it even possible?

I know people are probably going to use JEI with other mods usually, but it would be nice to group the items in recipe book somehow at least for lighter vanilla like mods.

I know bugger all about recipe book groupings.

    • They were already updated, and just to double check I even did a cleanup and fresh update from that same page. I'm quite sure drivers are not the problem here. 
    • i tried downloading the drivers but it says no AMD graphics hardware has been detected    
    • Update your AMD/ATI drivers - get the drivers from their website - do not update via system  
    • As the title says i keep on crashing on forge 1.20.1 even without any mods downloaded, i have the latest drivers (nvidia) and vanilla minecraft works perfectly fine for me logs: https://pastebin.com/5UR01yG9
    • Hello everyone, I'm making this post to seek help for my modded block, It's a special block called FrozenBlock supposed to take the place of an old block, then after a set amount of ticks, it's supposed to revert its Block State, Entity, data... to the old block like this :  The problem I have is that the system breaks when handling multi blocks (I tried some fix but none of them worked) :  The bug I have identified is that the function "setOldBlockFields" in the item's "setFrozenBlock" function gets called once for the 1st block of multiblock getting frozen (as it should), but gets called a second time BEFORE creating the first FrozenBlock with the data of the 1st block, hence giving the same data to the two FrozenBlock :   Old Block Fields set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=head] BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@73681674 BlockEntityData : id:"minecraft:bed",x:3,y:-60,z:-6} Old Block Fields set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} Frozen Block Entity set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockPos{x=3, y=-60, z=-6} BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} Frozen Block Entity set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockPos{x=2, y=-60, z=-6} BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} here is the code inside my custom "freeze" item :    @Override     public @NotNull InteractionResult useOn(@NotNull UseOnContext pContext) {         if (!pContext.getLevel().isClientSide() && pContext.getHand() == InteractionHand.MAIN_HAND) {             BlockPos blockPos = pContext.getClickedPos();             BlockPos secondBlockPos = getMultiblockPos(blockPos, pContext.getLevel().getBlockState(blockPos));             if (secondBlockPos != null) {                 createFrozenBlock(pContext, secondBlockPos);             }             createFrozenBlock(pContext, blockPos);             return InteractionResult.SUCCESS;         }         return super.useOn(pContext);     }     public static void createFrozenBlock(UseOnContext pContext, BlockPos blockPos) {         BlockState oldState = pContext.getLevel().getBlockState(blockPos);         BlockEntity oldBlockEntity = oldState.hasBlockEntity() ? pContext.getLevel().getBlockEntity(blockPos) : null;         CompoundTag oldBlockEntityData = oldState.hasBlockEntity() ? oldBlockEntity.serializeNBT() : null;         if (oldBlockEntity != null) {             pContext.getLevel().removeBlockEntity(blockPos);         }         BlockState FrozenBlock = setFrozenBlock(oldState, oldBlockEntity, oldBlockEntityData);         pContext.getLevel().setBlockAndUpdate(blockPos, FrozenBlock);     }     public static BlockState setFrozenBlock(BlockState blockState, @Nullable BlockEntity blockEntity, @Nullable CompoundTag blockEntityData) {         BlockState FrozenBlock = BlockRegister.FROZEN_BLOCK.get().defaultBlockState();         ((FrozenBlock) FrozenBlock.getBlock()).setOldBlockFields(blockState, blockEntity, blockEntityData);         return FrozenBlock;     }
